TapChae-K: Korea Transit Cards

Check your physical South Korean transit cards in one app. See your balances, top-ups and fares, and the journeys behind them.

Whether you are visiting Korea or living here, TapChae-K helps you make sense of the records on your card. Hold your card to the back of your iPhone to read its available information. Scan regularly to build your saved travel history.

Your cards, together
Use one card or add several, give them meaningful names and switch between them with a tap. Check the balance read from each stored-value card.

Journeys, day by day
• See recorded locations, journey distance and travel time.
• Follow transfers grouped into a journey.
• Review your travel with charts and fare, distance and time totals.
• Give locations your own names and add personal notes.

Top-ups and fares, in one view
Browse transactions read from your card, including top-ups and transit charges, with the recorded balance after each transaction.

Pass details from your card
View the pass type and validity dates read from your supported physical pass card.

Supported cards
Works with One Card All Pass cards and supported physical pass cards, including:
• T-Money (Tmoney, 티머니), and T-Money based cards such as WOWPASS
• EZL, formerly Cashbee, and EZL based cards such as Korea Travel Card, Kona Card and Woka Card

Quick card guides
Find practical answers on where to use your card, how to top it up and how refunds work.

Scan when you choose
Keep your card in the clear case on the back of your iPhone. TapChae-K reads it when you ask: open the app, tap "Scan Card" and hold the card to the back of your iPhone. If the last scan shows no tap-out, a reminder appears on the home screen.

Your records stay on your iPhone
No account needed. The balances and journeys recorded from your card, and your notes, are kept on your device, not on our servers, and are gone when you delete the app.

Ads and Premium
The app is supported by ads. A one-time Premium purchase removes ads, with no subscription or recurring charges. Premium also adds:
• Date filters for your journeys.
• Journey export to your calendar.
• Card data export as Markdown, PDF or CSV.
• Privacy Lock using your device's screen lock.
• More customisation, including how journeys are listed by day.
